If you missed the biggest news on the Internet this week, a huge bug was discovered in one of the Internet's most used security systems, and it went undetected for two years (get more info and a checklist of things to do in our write up here.) So, you're going to need to change the passwords of some of your most widely used websites — but you're going to have to wait until those websites fix the bug themselves, because changing your password before then won't matter.

Mashable compiled some of the biggest websites so far that you need to change your passwords on, and are clear to do so. Here are a few of them (go here for the complete list).

What Passwords to Change Now

  • Facebook
  • Tumblr
  • Google/Gmail (though the company says you're okay if you don't)
  • Yahoo!
  • GoDaddy
  • Intuit
  • Dropbox
  • Minecraft
  • OkCupid
  • SoundCloud
  • JDate
  • Christian Mingle
  • Wunderlist

Many of the top banks weren't affected, it still would be wise to update your password (and do so regularly.)
